RAM Charger has gone through name changes over the years:
OptiMem - all version 1.
OptiMem RAM Charger - all version 2
RAM Charger - all version 3
RAM Charger 8 - all version 8
There are a number of way you can determine what version
of RAM Charger you have:
If you have the RAM Charger "Heads-Up" window open,
then you must close it to avoid a MacOS bug. Then, do a find
file for "OptiMem" and/or "RAM Charger". Pick a file of one
of these exact names in your extensions or control panels
folder. You should have only one. Do a "Get Info" on the
If you get a version "N/A", then you must restart your
computer and be sure the "Heads-Up" window is closed before
doing a Get Info. If the control panel is open showing the
"Heads-Up", then the Finder cannot get the version and will
continue to report version "N/A" until the computer is
restart (this may be fixed in more recent versions fo Mac
OptiMem (version 1) shows the version at the bottom
of the Control Panel.
Some intermediate version of RAM Charger do not show the
version in the control panel.
Most later versions of OptiMem RAM Charger, and RAM
Charger show the version in the "Heads-Up" window. This is
accessed from the Control Panels folder in earlier versions
of OptiMem RAM Charger and RAM Charger, and accessed from
the RAM Charger Pull-Down Menu in the menu bar in RAM
Charger 8 (which opens the RAM Charger control panel from
the extensions folder).
In OptiMem RAM Charger and RAM Charger, you can
select "About RAM Charger Settings" from the Apple Menu when
when the "RAM Charger Settings For Individual Applications"
window is open. The version is displayed in the lower right.
With any purchase of OptiMem, OptiMem RAM Charger,
or RAM Charger, you are provided with a license called a
"serial ID". If you purchased directly from Jump Development
Group, then this license would have been sent to you printed
along on the same 8 1/2 x 11 sheet of paper with your
transaction receipt, or in an email message if you purchased
electronically - either way we have it on file in our
database. If you purchased directly from xyz, your
license is printed inside the front of your manual. If you
purchased from any other outlet, your license was provided
in the box on a 6 x 5 sheet of paper, perforated for one
half to be mail back in - and perhaps we have it on file in
